Description

Technical Field

[0001] The utility model relates to the technical field of production and manufacturing of four-way valves, in particular to a riveting assembly line for four-way valve core iron components. Background Art

[0002] Four-way valves are widely used in air conditioners, water heaters and other systems to switch the refrigerant flow path in the system, thereby achieving the cooling, heating and defrosting functions of the entire system. The four-way valve consists of a main valve and a pilot valve. Figure 9 and Figure 10 As shown, the pilot valve 9 includes a core iron 71, a drag frame 72, a sliding bowl 91, a spring 92 and a head 93. During the production process, the drag frame 72 and the core iron 71 need to be riveted to form a core iron assembly 7. At present, the riveting operation of the core iron assembly is completed by a semi-automatic assembly line. The specific operation process is that the core iron and the drag frame are loaded onto the riveting machine. After the riveting machine completes the riveting and unloading, the staff takes the riveted core iron assembly and uses the inspection tool to perform parallelism inspection, and the good products are stacked in the material box. The defects of using the above semi-automatic assembly line are: (1) one staff member is required for each semi-automatic assembly line, which has high labor costs; (2) this staff member needs to complete the work of loading, parallelism inspection and unloading into the material box, which has high labor intensity. After working for a long time, the human body is easily tired, resulting in reduced work efficiency; (3) the use of the inspection tool by hand during parallelism inspection requires high skills of the staff; (4) the semi-automatic assembly line is arranged in a straight line, which occupies a large area of workshop space. For example, Chinese invention patent CN 104889268A, published on September 9, 2015, is titled "A Four-Way Reversing Valve Core Iron Component Processing Equipment and Process." It discloses a machine base with a feed port on one side and a discharge port on the other. A conveyor belt connecting the feed port and the discharge port for conveying workpieces is provided on the base. A pre-assembly station, a press-fit station, and a riveting station are sequentially provided on the base from the feed port to the discharge port. The pre-assembly station is equipped with a drag rack component loading device, a core iron loading device, and a pressing device for combining the drag rack component and the core iron component.

[0042] like Figure 1 and Figure 3 As shown, based on the above embodiment, a debris collection box 6 is further provided on the top of the box body 1 below the first riveting machine 43 and the second riveting machine 45. Since the first riveting machine 43 and the second riveting machine 45 are prone to generate iron chips when riveting the drag frame 72 and the core iron 71, the iron chips falling on the top of the box body 1 will affect the cleanliness of the equipment. The debris collection box 6 can collect the fallen iron chips to ensure the cleanliness of the equipment.

[0043] Based on the above embodiment, a touch screen is further fixedly mounted on the housing 1, and a control unit is housed within the housing 1.

When the riveting line is to be used, first turn on the air source, hydraulic source, and main power supply for the equipment.

[0044] like Figures 1 to 10As shown, during the specific work, (1) preparation, the staff places the first material box 81 filled with core iron 71 on the first mounting frame 412 of the core iron feeding mechanism 41, and then fixes the first material box 81 on the first mounting frame 412 by tightening the knob 4121. The staff places the drag rack 72 in the vibration disk 422 of the drag rack feeding mechanism 42. The staff places the empty second material box 82 on the second mounting frame 474 of the good product collection mechanism 47, and then fixes the second material box 82 on the second mounting frame 474 by tightening the knob 4121. (2) Core iron loading: the core iron 71 in the first material box 81 on the core iron loading mechanism 41 comes out from the outlet, and then slides along the first channel 414 into the receiving groove 413. Then, the first cylinder 415 works, and the piston rod 4151 of the first cylinder 415 drives the first push rod 416 to move toward the placement rack 3 corresponding to the receiving groove 413 on the rotating table 2. The first push rod 416 pushes the core iron 71 in the receiving groove 413 into the placement groove 31 of the placement rack 3. (3) The drag rack is loaded and pre-pressed. The reduction motor on the box body 1 drives the rotary table 2 to rotate clockwise by one station angle, so that the placement rack 3 with the core iron 71 placed on it corresponding to the core iron loading mechanism 41 is rotated to correspond to the drag rack loading mechanism 42. Then, the vibration plate 422 works to transport the drag rack 72 to the second channel 423 of the drag rack loading mechanism 42. The drag rack 72 slides along the second channel 423 to the first turning point position. Then, the second cylinder 424 works, and the piston rod 4151 of the second cylinder 424 drives the push block 425 toward The pusher block 425 pushes the drag rack 72 located at the first turning point to the second turning point. Then, the third cylinder 426 works, and the piston rod 4151 of the third cylinder 426 drives the second pusher rod 427 to move toward the placement rack 3 corresponding to the second channel 423 on the rotating table 2. The second pusher rod 427 pushes the drag rack 72 located at the second turning point in the second channel 423 into the placement groove 31 of the placement rack 3, and cooperates with the core iron 71 in the placement groove 31 to realize the pre-pressing of the core iron 71 and the drag rack 72. (4) One-time riveting: the reduction motor on the box body 1 drives the rotating table 2 to rotate clockwise by one working angle, so that the placement rack 3 corresponding to the drag rack feeding mechanism 42, on which the pre-pressed core iron 71 and the drag rack 72 are placed, rotates to correspond to the first riveting machine 43. Then, the first riveting machine 43 works to rivet the core iron 71 and the drag rack 72 once. The riveting position is the riveting part 711 on the core iron 71, and a semi-finished core iron assembly is obtained. The iron chips generated during the riveting process fall into the debris collection box 6 below the first riveting machine 43.(5) Flipping, the reduction motor on the box body 1 drives the rotary table 2 to rotate clockwise by one working angle, so that the placement rack 3 on which the semi-finished core iron assembly is placed corresponding to the first riveting machine 43 is rotated to correspond to the flipping mechanism 44, and then the conveying cylinder 444 on the flipping mechanism 44 works, and the piston rod of the conveying cylinder 444 drives the rotating cylinder 442 to move toward the placement rack 3 on which the semi-finished core iron assembly is placed on the rotary table 2, until the slot 4431 on the rotating head 443 of the rotating cylinder 442 is engaged with the dragging rack 72 of the semi-finished core iron assembly, and then the rotating cylinder 442 works, and the output shaft 4421 of the rotating cylinder 442 drives the rotating head 443 to rotate 90 degrees, and the rotating head 443 drives the semi-finished core iron assembly to flip 90 degrees. (6) Secondary riveting: the reduction motor on the housing 1 drives the rotating table 2 to rotate clockwise by one station angle, so that the placement rack 3 on which the semi-finished core iron assembly turned 90 degrees is placed, which corresponds to the flipping mechanism 44, rotates to correspond to the second riveting machine 45. Then, the second riveting machine 45 works to perform secondary riveting on the core iron 71 and the dragging rack 72. The riveting position is the riveting part 711 on the core iron 71, and the core iron assembly is obtained. The iron filings generated during the riveting process fall into the debris collection box 6 below the second riveting machine 45. (7) Parallelism detection: the reduction motor on the housing 1 drives the rotating table 2 to rotate clockwise by one station angle, so that the placement rack 3 on which the semi-finished core iron assembly is placed, which corresponds to the second riveting machine 45, rotates to correspond to the detection mechanism 46. Then, the height gauge 461 of the detection mechanism 46 works. The height gauge 461 detects the parallelism of the dragging rack 72 of the core iron assembly and the core iron 71, and distinguishes between good core iron assemblies and defective core iron assemblies.(8) Unloading, the reduction motor on the box body 1 drives the rotating table 2 to rotate clockwise by one working angle, so that the placement rack 3 on which the inspected core iron component finished product is placed corresponding to the inspection mechanism 46 rotates to correspond to the unloading robot 48, and then the unloading robot 48 works; if the placement rack 3 contains good core iron components, the unloading robot 48 grabs the good core iron components and places them on the good product conveyor belt 51, and then the second motor 54 works to drive the good product conveyor belt 51 to move a distance of the diameter size of the good core iron components. When a row of good core iron components is placed on the good product conveyor belt 51, the fourth cylinder 476 works, and the piston rod 4151 of the fourth cylinder 476 drives the push plate 477 to move toward the second material box 82, and the push plate 477 pushes the row of good core iron components placed on the good product conveyor belt 51 into the second material box 82, and then the first cylinder 476 works. The cylinder 415 drives the push plate 477 to reset, and then the first motor 475 works, and the output shaft 4421 of the first motor 475 drives the screw 472 to rotate forward. The forward rotation of the screw 472 causes the nut 473 to move downward by a distance of the diameter size of the good core iron component, and the nut 473 drives the second material box 82 on the second mounting frame 474 to move downward by a distance of the diameter size of the good core iron component. This makes it convenient for the push plate 477 to push a row of good core iron components into the second material box 82 again, so that the good core iron components in the second material box 82 are neatly stacked in sequence in the vertical direction. When the second material box 82 is full, the staff replaces the empty second material box 82; if the core iron component on the placement rack 3 is defective, the unloading robot 48 will grab the defective core iron component and place it on the defective product conveyor belt 52, completing a complete core iron component 7 riveting process.
